Super bee rpm figures?

Admin wrote:Probably around the same RPMs as a good Babe Bee. The only difference I have seen between a super bee and a babe bee was the #1 (or P-40 on early models) cylinder instead of the #2 cylinder. Personally I would leave the engine in the plane and hang the plane on the ceiling or put it on a shelf. Maybe remove the engine to run it on a test stand for fun and then put it back.

I didn't know a Babe Bee from a red-backed product engine like my black Stuka had, but it flew good for a plastic plane. By then I was getting pretty proficient at roundy-round flying so it lasted a long time... in plastic plane years.
I always used my schoolyards to fly, so at recess at elementary and junior high, I used to walk around and occasionally find pieces of my planes. That's when I became such an expert gluer.
Was that Babe Bee different from an ordinary Bee? I've tried to figure out where all my engine parts originated, but no way to be sure.

Hi Nitro,

Nice P-40! Admin is right, wipe that baby down and put it on display.

The "Super Bee" should put out a little more RMP due to the twin intake ports.

I have a Babe Bee with P-40 stamped on the cylinder. Don’t remember how nor when I acquired it. (Never had the P-40 plane). I guessed, but wasn’t sure, that it was an engine intended for the P-40 plane. Didn’t know till now that it is apparently the equivalent of a super bee.

Is this numbering unique, i.e., are there any other engines that have the plane # stamped on the cylinder rather than the usual single digit designation?

The list reads: prop size / rpm / torque / thrust / b.h.p.
Babe Bee - Blue Can:
6x3 / 13,000 / 3.7 / 9.7 / .0477
5x3 / 17,500 / 2.5 / 9.9 / .0434
5x3 (3-blade) / 13,500 / 3.45 / 9.0 / .0462
Babe Bee - Racing Fuel:
6x3 / 13,000 / 3.8 / 9.5 / .0490
5x3 / 17,200 / 2.55 / 9.2 / .0435
5x3 (3-blade) / 13,600 / 3.6 / 9.2 / .0486

Super Bee - Blue Can:

That is a significant difference.

6x3 / 14,500 / 4.75 / 13.8 / .0684
5x3 / 18,600 / 3.7 / 13.5 / .0682
5x3 (3-blade) / 14,900 / 4.75 / 12.8 / .0702
Super Bee - Racing Fuel:
6x3 / 15,100 / 5.4 / 15.1 / .0810
5x3 / 19,200 / 4.1 / 13.5 / .0730
5x3 (3-blade) / 15,700 / 5.3 / 14.3 / .0825
